DRUM.

Application filed March 31, 1909.

To all whom it may concern:

Be it known that I, ATHERTON DARLING CONVERSE, a citizen of the UnitedStates, and a resident of lVinchendon, in the county of Worcester andState of Massachusetts, have invented a new and Improved Drum, of whichthe following is a full, clear, and exact description.

This invention relates to certain improvements in toy drums, and moreparticularly to improvements in the construction of the head and themeans for securing the same in place.

The object of the invention is to simplify the construction by formingthe hoop sections integral with the body and the head, and thus avoidthe necessity for employing` separate fastening means for the head.

In my improved construction, the head is formed with a hoop section atone end of greater diameter than the body of the drum, and the head isalso provided with a hoop section which engages with the hoop section ofthe body and 1s locked thereto to hold the drum in position.

Reference is to be had to the accompanying drawings, forming a part ofthis speciflcation, in which similar characters of reference indicatecorresponding parts in both the figures, and in which- Figure 1 is aside elevation of a drum constructed in accordance with my invention, aportion thereof being broken away; and Fig. 2 is an enlarged sectionthrough the hoop sections and head-securing means.

In the specific form of drum illustrated, I employ a body 10substantially cylindrical in form and constructed of sheet metal orother suitable material. The body at each end is enlarged to form twohoop sections 11, 11 of somewhat greater diameter than the lremainder ofthe body, each enlarged end being separated from the body by anoutwardly-extending connecting portion 12 constituting a shoulder. Asthe enlarged end portion 11 is of only slightly greaterdiameter than thebody, it gives the appearance of a hoop encircling the body. The drum isprovided with two heads 13, 13, each preferably formed of sheet metaland disposed within the body adjacent the corresponding enlarged end.The peripheral portion of the head is bent outwardly to form asubstantially cylindrical flange 14 constituting a Specification ofLetters Patent.

second hoop section and of such diameter as to fit closely within theenlarged end `of the drum. Each head 13 rests directly upon itscorresponding shoulder 12, and the outwardly-extending flange 14 whichconstitutes the inner drum section, extends outwardly within theenlarged end and serves to reinforce and strengthen the latter. Theouter edge of the enlarged end 11 is curved inwardly upon itself to forma flange or bead 15, which engages with the inner surface of the flange14 to conceal the free edge of the latter and prevent displacement ofthe head.

It will be noted that the outer hoop section 11 is provided with aninwardly-directed flange at one end in the form of the connecting wall12, which latter also serves as a seat for the drum head and is alsoprovided lwith an inwardly-directed flange at the opposite end in theform of the bead 15. The two flanges 12 and 15 lock the hoop section 14against any longitudinal movement, and the drum heads 13 are thus firmlyheld in place. The enlarged ends give the appearance of hoops and theterminal beads give the appearance of considerable thickness to thesehoops. The hoops are formed of double thickness so that they arecomparatively strong and not easily bent by rough or careless handling.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A metal drum, formed of three pieces or members, one of said memberscomprising a cylindrical body and two terminal hoops integral therewith,said hoops being separated from said body by annular shoulders, and theother two of said members each comprising a sheet metal drum head seatedupon its corresponding shoulder and having a peripheral metal flangeconcentric with the'adjacent hoop and in engagement with the innersurface thereof to reinforce the latter, the marginal edge of each hoopbeing bent inwardly and back upon itself to retain said drum head flangein position and against said shoulder.

2. A sheet metal drum, including a substantially cylindrical body havinga hoop at one end thereof and separated therefrom by a shoulder, a sheetmetal drum head seated upon said shoulder and having an annular flangeconcentric with said hoop and in engagenient With the inner surfacethereof to name to this specification in the presence of reinforce thelatter, the outer or free edge two subserlblng Witnesses.
